IMPROVEMENT IN HOT-WATER HEATING APPARATUS FOR RANGES.

Specification forming part of Letters Patent No. 134,765, dated January14, 1873.

To all whom it may concern Be it known that I, HENRY L. PALMER, of thecity, county, and State of New York, have invented certain Improvementsin Heating Apparatus, of which the following is a specification:

This invention consists in heating the apartments of a building by meansof a radiator heated by steam or hot water conveyed to it by pipes fromthe water-back of a cookingstove or range, and situated in anair-chamber, from which the heated air passes through pipes into theapartments to be warmed, the cold air being introduced into theair-chamber by pipes or other equivalent means. i

In the accompanying drawing, Figure 1 is a front view, partly insection, of a range and appurtenances illustrating the invention; andFig. 2 is a horizontal section on the line 40 iv, Fig. 1.

or represents a range or cooking-stove provided with a water-back, B,from which the pipes b b c c branch and extend into the reservoir orboiler d, surrounded by the casing c, and into the radiator m, situatedin the airohamber n, which may be made in the jamb of the fire-place orin any other convenient place. 0 is a pipe connected with theair-chamber a, and o, a pipe connected with the space containing hot airbetween the boiler d and its casin g e. These pipes are carried to theapartments to be heated in the usual manner, and convey the hot airsurrounding the radiator or boiler to the rooms desired to be warmed. pp are pipes which extend respectively from the lower part of theair-chamber a, in which the radiator is situated, and from the spacebetween the boiler and its casing, to the outside of the building, or tothe lower rooms for the supply of cold air. If preferred, cold air maybe introduced from the room in which the range is situated. Cold wateris introduced into the boiler by a feed-pipe in the usual manner, andpasses thence into the water-back, where it becomes heated, andcirculates through the pipes b b c 0 connecting it with the radiator mand boiler 11. The hot water and steam thus generated heats the air inthe chambers in which the radiator and boiler are situated, which isconveyed by means of the pipes 0 o to the apartments to be heated, itsplace being filled by cold air passing in through the pipes 19 p. Thewaterboiler d may be the common hot-water reservoir for kitchen andbathing purposes. This does not constitute an essential part of myinvention.

By surrounding it with a casing provided with air-pipes p and o the saidboiler may be made to serve as the radiator by which air is heated, or aradiator of any preferred form may be employed, as illustrated at m, thesaid radiator being filled with either water or steam, and thegeneration of the steam or heating of the water being effected, ifpreferred, by a separate water back or coil of any form distinct fromthat which is employed to heat the water in the customary boiler. Thiswater-back may, if preferred, be supplied from a separate reservoir, orit may be in direct connection with the supply-pipe.

To prevent excessive pressure and cause a constant circulation throughthe radiator, the water or steam may be returned to the reservoir orboiler, or steam may be discharged into the smoke flue or chamberthrough a pipe guarded by a safety-valve.

The boiler and its casing are but one form of my-invention.

By the use of the casing the radiation of heat of the boiler isutilized, and in warmer days, whenthe heat is not wanted in other rooms,by closing the air-pipes 0 or p, the upper rooms are not warmed, and thetemperature of the kitchen itself is kept down.

I claim as new and of my invention- 1. The water-back B, reservoir d,radiator m, and connecting-pipes b b c 0 combined and arrangedsubstantially as herein set forth, so that the said water-back will actas a circulating as well as a heating medium.

2. The combination of the reservoir (1, the radiator m placed within achamber adjacent to the range, the water-back or heating-coil Binterposed between the said reservoir and radiator, the connecting-pipesb b c e permitting a constant circulation of water through thewater-back, between the reservoir and radiator, the pipe pfor supplyingcold air to the ranged substantially as described, to provide chamberat, and the pipe 0 for conducting heatfor employing the Water-boiler dfor heating ed air from the said chamberv to apartments purposes.

to be warmed all substantially as herein set H. L. PALMER. forth.Witnesses:
